Abstract

Se validó un instrumento diseñado para medir la adherencia al tratamiento hipertensivo conformado por 10 ítems tipo Escala Likert. Se evaluó la validez de constructo mediante análisis factorial y confiabilidad por medio del Alpha de Cronbach. El análisis factorial permitió agrupar los ítems en torno a los factores que componen dicho constructo. El valor de Alfa obtenido (0,515) corresponde a un valor moderado lo que significa que el instrumento puede ser utilizado como técnica adecuada de recolección de datos.

An instrument was designed to measure the adhesion to the hypertension treatment using a tool composed of 10 items Likert-type scale. The construct validity through factorial analysis and reliability by using Cronbach's Alpha was evaluated. The factorial analysis allowed the grouping of the items around the factors that make up the construct. The alpha value obtained (0.515) corresponds to a moderate value which means that the instrument can be used as a proper technique to collect data.
